Could be something as simple as the connection came unplugged. If not, disconnect it at the lug and check it with a test probe to see is there power from the harness to the motor. If no power, check fuses and connection at the sending unit.

Is the parking brake engaged?

Change both axel bearings at the same time. The pinion bearing can be tested by slowly turning the drive shaft by hand and listening for any rough spots. It could be a carrier bearing or a bad U joint too. Isolate it by dropping the drive shaft and turning the pinion yoke by hand. If there is a problem, you'll be able it feel it. Then look at the drive shaft for worn carrier bearing and U joints.

You might want to check the ball joint. None of them have grease zerks and can dry out. They will cause a noise when turning or hitting a bump, if really bad. Hope this helps.

You will need to contact your local dealer with the Vin number of your truck & possibly the make of your radio. When a radio locks the dealer has the code to unlock the radio, just give them a call & you should have your radio working in no time.

Hi Anita:
If it had been running fine up until the maintenance that you describe, I would be checking what had been done.
-The first concern would be the oil used, and the amount. Is it possible that it was overfilled or that the wrong kind of oil was used?
Please reply as a comment to this post and I'll try to assist you.

Probably not... For some reason license plate light wiring and sockets are VERY prone to corrosion. Make sure to check the light sockets and try to get to the wiring close to them, your problem is more than likely very close to the lights.
